Referring to FIG. 1, which shows a schematic structural view of anenvironmental-friendly artificial leather according to a firstembodiment of the present disclosure. The environmental-friendlyartificial leather 10 in the first embodiment of the present disclosureincludes a first fiber web 11, a filament fabric 12, and a second fiberweb 13.

In some embodiments, the first fiber web 11 is a meltblown fiber web,and a material of the first fiber web 11 is thermoplastic polyurethane(TPU). Preferably, a Shore hardness of the TPU is greater than 60A andless than 40 D. When the Shore hardness is greater than 40D, thehardness of the TPU is excessively high, and therefore, a completedcomposite structure sheet is excessively hard, delivers paper liketouch, and does not deliver artificial leather touch. When the Shorehardness is less than 60A, a physical property apparently degradesbecause the TPU is excessively soft.

In addition, to enable the environmental-friendly artificial leather 10to deliver good hand feel of an imitation leather, a fiber fineness ofthe first fiber web 11 should be controlled to be 1 to 6 deniers, and athickness of the first fiber web 11 should be controlled to be 0.3 to1.0 mm.

The filament fabric 12 is disposed on the first fiber web 11. In someembodiments, the filament fabric 12 can be manufactured through warpknitting, weft knitting, knitting, or tatting, and preferably, amaterial of the filament fabric 12 is thermoplastic polyurethane (TPU).

Furthermore, to enable the environmental-friendly artificial leather 10to achieve high physical properties (to be specific, a high tensilestrength and high tearing strength), a fiber fineness of the filamentfabric 12 should be controlled to be 20 to 600 deniers.

The second fiber web 13 is disposed on the filament fabric 12. In someembodiments, the second fiber web 13 is a meltblown fiber web, and amaterial of the second fiber web 13 is thermoplastic polyurethane (TPU).Preferably, a Shore hardness of the TPU is greater than 80A and lessthan 65 D. When the Shore hardness is greater than 65 D, the hardness ofthe TPU is excessively high, and therefore, when grinding and teasingare performed, hairiness is excessively stiff, and does not deliverartificial leather touch. When the Shore hardness is less than 80A,there is no grinding property because the TPU is excessively soft.

FIG. 2 shows a schematic view of a second fiber web with a teasingstructure of an environmental-friendly artificial leather according to afirst embodiment of the present disclosure. With reference to FIG. 1 andFIG. 2, to enable the environmental-friendly artificial leather 10 todeliver hand feel of a teasing leather, surface grinding can beperformed on the second fiber web 13 to form a teasing structure 13W.

In addition, to enable the teasing structure 13W of the second fiber web13 to satisfy a fine hairiness requirement, a fiber fineness of thesecond fiber web 13 should be controlled to be 0.05 to 3 deniers, and athickness of the second fiber web 13 should be controlled to be 0.3 to1.0 mm.

Preferably, a Shore hardness of the TPU is greater than 60A andless than 40 D. When the Shore hardness is greater than 40 D, thehardness of the TPU is excessively high, and therefore, a completedcomposite structure sheet is excessively hard, delivers paper liketouch, and does not deliver artificial leather touch. When the Shorehardness is less than 60A, a physical property apparently degradesbecause the TPU is excessively soft.

In addition, to enable the environmental-friendly artificial leather 20to deliver good hand feel of an imitation leather, a fiber fineness ofthe first fiber web 22 should be controlled to be 1 to 6 deniers, and athickness of the first fiber web 22 should be controlled to be 0.3 to1.0 mm.

When the Shore hardness is greater than 65 D, the hardness ofthe TPU is excessively high, and therefore, when grinding and teasingare performed, hairiness is excessively stiff, and does not deliverartificial leather touch. When the Shore hardness is less than 80A,there is no grinding property because the TPU is excessively soft.

FIG. 6 shows a schematic view of a second fiber web with a teasingstructure of an environmental-friendly artificial leather according to asecond embodiment of the present disclosure.
